Pricing for enterprise?

Hi,

I have done some PoC projects and playing around a bit with the Neo4j over the last 3-4 years and now starting a bit more serious project and considering using Neo4j for this project but things have changed a bit since I last used it on the licensing model.

I will be ok with the community edition to start with but if things kick off I hopefully will need a lot of the enterprise functionality but the fact there is no indication of costs at neo4j.com, I am a bit reluctant to choose neo4j with the too many unknowns.

I do understand pricing might be complex for very large projects but a price example for reference installation I believe would be good.

And thanks for a great product!

Best Regards,
Stefan
